This plugin creates a configuration page that prompts the user to select features to hilite based on their attributes (also known as feature tags in BioPerl parlance). You specify which attributes to present in a [AttributeHiliter:plugin] configuration track with a single "attributes" option. The value of this option is a space-delimited list of attributes to present to the user.

A more sophisticated example using popup menus to select particular attributes from a controlled vocabulary would be easy to write.
